    In:  Supplement to: Andrews, Anthony J (1979): On the effect of low-temperature seawater-basalt interaction on the distribution of sulfur in oceanic crust, layer 2. Earth and Planetary Science Letters, 46(1), 68-80, https://doi.org/10.1016/0012-821X(79)90066-9
    Publication Date: 2024-05-15
    Description: A detailed geochemical-petrological examination of layer 2 basalts recovered during Leg 37 of the DSDP has revealed that the original distribution, form and abundance of igneous sulfide have been profoundly altered during low-grade oxidative diagenesis. The net result appears to have been a rather pervasive remobilization of igneous sulfide to form secondary pyrite accompanied by a bulk loss of sulfur equivalent to about 50-60% of the original igneous value, assuming initial saturation. It is suggested that during infiltration of seawater into the massive crystalline rock, igneous sulfide has experienced pervasive oxidation, under conditions of limited oxidation potential, to form a series of unstable, soluble sulfur species, primarily in the form of SO3[2-] and S2O3[2-]. Spontaneous decomposition of these intermediate compounds through disproportionation has resulted in partial reconstitution of the sulfur as secondary pyrite and the generation of SO4[2-] ion, which, due to its kinetic stability, has been lost from the basalt system and ultimately transferred to the ocean. This model not only satisfies the geochemical and petrological observations but also provides a suitable explanation for the highly variable delta34S values which characterize secondary sulfides in deep ocean floor basalts.

    Description: DSDP Leg 337 was planned as an attemp at deep penetration of the igneous section of the oceanic crust on the western flank of the FAMOUS (Franco- American Mid-Ocean Undersea Study) area of the Mid-Atlantic Ridge at 36°N. Site 332 is located in Deep Drill Valley approximately 30 km west of the axis of the Mid-Atlantic Ridge at 36°52'N latitude. The principal goal at this site was deep penetration into layer 2 of the ocean crust by multiple re-entry. Site 334 was drilled on a steep east-facing slope in a small, deep basin near the middle of magnetic anomaly 5. In this area, breccias with gabbro and peridotite clasts in a nannofossil-foram ooze matrix are interlayered with the plutonic rocks and may reflect exposure of a melange in or near the Median Valley of the Mid- Atlantic Ridge prior to burial by later basaltic extrusions.

    Description: Titanomagnetites separated from 15 different rock samples (including ocean-floor basalts from DSDP Legs 37, 45 and 46) were analyzed together with whole-rock samples by instrumental neutron-activation analysis for Sc, Cr, Co, Zn, Hf, Ta, Th and the REE La, Ce, Nd, Sm, Eu, Gd, Tb, Dy, Tm, Yb and Lu. In titanomagnetities from ocean-floor basalts and some other rocks, REE are enriched with respect to the whole-rock composition by factors of between 1.5 and 3 for light REE and between 1.0 and 1.9 for heavy REE; that is, REE with larger ionic radii are preferentially incorporated into the magnetite lattice. Three magnetite samples are REE depleted. Their whole-rock samples contain P in appreciable amounts, so apatite, an important REE-accumulating mineral, could have captured REE to some extent. All titanomagnetites show a marked negative Eu anomaly, this is most probably caused by discrimination of Eu(2+) from the magnetite lattice. Co, Zn, Hf and Ta are significantly enriched in magnetites. The distribution behaviour of Sc and Cr is masked chiefly by the crystallization of clinopyroxene and therefore is not easy to estimate. Ulvöspinel contents of about 70% for the titanomagnetites from ocean-floor basalts were estimated from qualitative microprobe analysis. Ulvöspinel contents of all other samples varied in a wide range from 20% to about 90%. No correlation could be observed between this and the REE contents of the magnetites. Ilmenite exsolution lamellae could only be observed in titanomagnetites from a doleritic basalt from Leg 45.

    Publication Date: 2024-05-15
    Description: 143Nd/144Nd ratios have been determined on 37 samples of oceanic basalt, with a typical precision of +/- 2-3 * 10**-5 (2 sigma). Ocean island and dredged and cored submarine basalts are included for which reliable measurements of 87Sr/86Sr ratios exist in the literature or have been measured as part of this study. A strong negative correlation exists between 143Nd/144Nd and 87Sr/86Sr ratios in basalts from Iceland and the Reykjanes Ridge, but such a clear correlation does not exist for samples from the Hawaiian Islands. However, when other ocean island basalts from the Atlantic are included there is an overall correlation between these two parameters. Increases and decreases in Rb/Sr in oceanic basalt source regions have in general been accompanied by decreases and increases respectively in Sm/Nd ratios. The compatibility of the data with single-stage models is assessed and it is concluded that enrichment and depletion events, which are consistent with transfer of silicate melts, are responsible for the observed variation.

    Publication Date: 2024-05-15
    Description: Comparison of rates of accumulation of organic carbon in surface marine sediments from the central North Pacific, the continental margins off northwest Africa, northwest and southwest America, the Argentine Basin, and the western Baltic Sea with primary production rates suggests that the fraction of primary produced organic carbon preserved in the sediments is universally related to the bulk sedimentation rate. Accordingly, less than 0.01% of the primary production becomes fossilized in slowly accumulating pelagic sediments [(2 to 6 mm (1000 y)**-1] of the Central Pacific, 0.1 to 2% in moderately rapidly accumulating [2 to 13 cm (1000 y)**-1] hemipelagic sediments off northwest Africa, northwest America (Oregon) and southeast America (Argentina), and 11 to 18% in rapidly accumulating [66 to 140 cm (1000 y)**-1] hemipelagic sediments off southwest America (Peru) and in the Baltic Sea. The emiprical expression: %Org-C = (0.0030*R*S**0.30)/(ps(1-Theta)) implies that the sedimentary organic carbon content (% Org-C) doubles with each 10-fold increase in sedimentation rate (S), assuming that other factors remain constant; i.e., primary production (R), porosity and sediment density (ps). This expression also predicts the sedimentary organic carbon content from the primary production rate, sedimentation rate, dry density of solids, and their porosity; it may be used to estimate paleoproductivity as well. Applying this relationship to a sediment core from the continental rise off northwest Africa (Spanish Sahara) suggests that productivity there during interglacial oxygen isotope stages 1 and 5 was about the same as today but was higher by a factor of 2 to 3 during glacial stages 2, 3, and 6.

    Description: Oceanic crustal drilling by R. V. Glomar Challenger at 15 sites in the North Atlantic has led to a complex picture of the upper half kilometer of the crust. Elements of the picture include the absence of the source for linear magnetic anomalies, marked episodicity of volcanic activity, ubiquitous low temperature alteration and evidence for large scale tectonic disturbance. Comparison sections in the Pacific and much deeper crustal drilling are needed to attack problems arising from the North Atlantic results.

    Description: Refractory megacrysts of olivine, plagioclase, chromian diopside and Cr-Al spinel, which were not in equilibrium with the host oceanic tholeiite on eruption, are present in samples from several dredge sites and DSDP drill sites in the Atlantic and Pacific Oceans. They have multiple origins: (1) cognate or accidental mantle fragments; (2) relict fragments from fractional crystallization of parental liquids considerably more primitive than oceanic tholeiite; and most commonly (3) the fractional crystallization products of such liquids mixed with oceanic tholeiite magma. Melt inclusions in chrome-spinel phenocrysts provide evidence for this postulated Mg- and Ca-rich magma which has counterparts in the Scottish Tertiary Province and in west Greenland.

    Description: The Aminoil Group drilled a 10,000 ft - well a few kilometers off the Krakatau volcano in 1973. The well bottomed in Pliocene sediments after penetrating a more than 8,000 ft thick Upper Pliocene section of mainly claystones with interbedded sand-, siltstones and pyroclastics. On the basis of temperature surveys and BHT's measured during logging, a static formation temperature in excess of 450° F was extrapolated for the bottom of the hole. Tue high temperatures caused some deterioration in the mud properties, but otherwise no serious drilling problems. Owing to overpressures a high salinity oil mud and controlled drilling had to be employed. The well was P&A because no economic hydrocarbon accumulations could be expected in the high temperature regimes.

    Publication Date: 2024-04-16
    Description: Bulk composition of ferromanganese nodules from the pelagic environment of the Pacific Ocean is apparently related to nodule-growth rate, sediment-accumulation rate, and biologic productivity in the overlying seawater. Nodules with a high Mn/Fe ratio and high Ni and Cu concns tend to occur in areas where primary productivity in the surface layer of the ocean is high and the sediment accumulation rate low. They may have a Mn/Fe ratio as low as one and accrete at rates as low as 1 mm per 1 million years. Nodules with a larger Mn/Fe ratio apparently have growth rates that are greater by as much as a factor of 10.

    In:  Supplement to: Carter, Lionel (1979): Significance of Unstained and Stained Gravel on the Newfoundland Continental Slope and Rise. Journal of Sedimentary Research, 49(4), 1147-1158, https://doi.org/10.1306/212F78D3-2B24-11D7-8648000102C1865D
    Publication Date: 2024-04-16
    Description: The continental slope and rise, east of Newfoundland, accommodates two distinct gravel populations. The upper slope (300-700 m depth) population is characterized by unstained, granules to boulders of predominantly granitic and terrigenous sedimentary compositon that show affinity to Paleozoic and Proterozoic rocks of Newfoundland and areas further north. The rise (2,500-〉3,000 m depth) population consists of iron- and ferromanganese-stained granules to cobbles composed mainly of carbonate that presumably has been derived from the high Canadian Arctic. The rise clasts are further distinguished in that they are finer grained, slightly more rounded and more altered by solution and/or boring organisms than their shallower water counterparts. The upper slope gravel has been reworked from underlying sediments, and deposited from ice rafts, and both processes are probably continuing today. Gravel on the rise has been concentrated through winnowing of middle Holocene sediments by the Western Boundary Undercurrent which appears to have been operative as a winnowing agent since about 4,000 to 5,000 y BP. The undercurrent has also affected the distribution of stained gravel which is most common and most intensely stained beneath a fast-flowing undercurrent core where environmental conditions resemble those documented for deep-sea, ferromanganese nodule fields.

    Description: Die Humifizierungswechsel nordwesteuropäischer Hochmoore sind als Schwarztorf-Weißtorf-Kontakte‚ Rekurrenzflächen oder "WEBERscher Grenzhorizont" bekannt. Eine ähnliche Erscheinung wurde auf Gough Island im Südatlantik entdeckt. In den dortigen terrainbedeckenden Mooren gibt es ebenfalls einen Schwarztorf-Weißtorf-Kontakt. Diese terrainbedeckenden Moore von Gough Island sind nährstoffreicher als unsere nordwesteuropäischen Hochmoore. Ursache dieses Phänomens ist wahrscheinlich die Nährstoffanreicherung durch den Kot der zahlreichen Seevögel.
    Description: The changes of humification of North-West European bogs are known as dark peat/light peat contacts, recurrence horizons or "WEBERscher Grenzhorizont". A similar phenomenon has been discovered on Gough Island in the South Atlantic. There is also dark peat/light peat contact in the blanket bogs over there. These blanket bogs on Gough Island are richer in nutrients than our North-West European bogs. The cause of this phenomenon is the accumulation of nutrients through the dropping of the numerous seabirds.

    In:  Supplement to: Leclaire, Lucien; Perseil, E A (1979): Minéralogie, composition chimique et milieux de sédimentation de concrétions polymétalliques dans l'océan Indien = Mineralogy, chemical composition and sedimentation environment of manganese nodules from Indian Ocean. In: Lalou, C (Ed) La Genèse des nodules de manganèse. Centre National de la recherche Scientifique (CNRS), Gif-sur-Yvette, France, 23-37, hdl:10013/epic.46398.d001

    Description: Mineralogical analysis of manganese nodules and crusts collected from Indian ocean aboard Marion Dufresne points to a depth and regional control upon the manganese oxide association: vernadite - birnessite and vernadite - todorokite. Moreover, progressive changes in the vernadite/birnessite ratio as a function of time is clearly seen. Magnetite and titano-magnetite in quantities similar to those of framboidal pyrite in manganese nodules are outlined for the first time. Study of the distribution of metals (Mn, Fe, Ni, Cu, Co) shows a strong latitudinal and regional dependence that may be connected to high productivity zones and to bottom water properties. The problem of mineralogical control on the chemical composition is approached. Finally, it results that any interpretations taking into account all these data haveway to give to the variability of sea-water properties (pH, oxygenation, motions) the prominent control upon manganese nodules composition.

    Description: Durch Untersuchung des Wasserhaushaltes einer Deutschen Hochmoorkultur wird der Einfluß von Trockenjahren dargelegt. Wie Bodenfeuchtigkeitsuntersuchungen mit Tensiometern zeigen, bleiben Moorböden zunächst lange feucht und trocknen dann nur in der durchwurzelten Schicht aus. Wenige Dezimeter darunter bleibt der Moorboden fast wassergesättigt. Wie gezeigt werden konnte, ist dies eine Folge der kapillaren Wasserleitfähigkeit der Torfe. Der Austrocknung der durchwurzelten Schicht kann durch schweres Walzen begegnet werden. Hierzu werden Ergebnisse zur Bodenfeuchteänderung durch Walzen mitgeteilt.
    Description: Dry years also influence the water balance of peat soils. This could be shown by investigations on a German raised bog cultivation. Measurements of soil moisture with tensiometers indicated a long period with sufficient water content. After this period dryness appeared in the rooted zone only, but a few decimeters below this zone the peat soil was nearly saturated. This follows from the unsaturated flow conditions of the peat soils. The drying out of the rooted zone can be reduced by heavy rolling. This had been proved by the measurement of soil moisture during the rolling trial.

    Description: Es wird der Lebenslauf der ältesten Moorforschungsstätte von 1877 bis 1977 vorgestellt. Die Gründe zur wissenschaftlichen Bearbeitung der Moore waren schon immer vielschichtig. So wird aus der Geschichte der Moor-Versuchsstation in Bremen deutlich, dass Naturwissenschaftler, Ökologen und Agrarwissenschaftler gemeinsam an der Erforschung der Eigenschaften von Mooren und Torfen mit dem Ziel ihrer optimalen Nutzung interessiert sind. Es wird aber auch deutlich, wie stark die Erkenntnisse der Moorforschung andere Wissenschaften berühren. Darin kommt die interdisziplinäre Stellung der Moor- und Torfkunde zum Ausdruck.
    Description: The curriculum vitae of the oldest institute of moor and peat research, the Moor-Versuchsstation in Bremen, from 1877 till 1977 is presented. The motives for scientific work about bogs and fens all over the time have been multi-purposed. The history of this institute shows, that scientists, oecologists and agriculturists together are interested in the qualities of moor and peat and their usage to the best of ones knowledge. But, it is shown too, how results of moor and peat research other sciences concern. By this the interdiszipline role of moor and peat research is expressed.

    Description: Im Rahmen dieser Arbeit wurden Schichtglieder der nordpenninischen Feuerstätter Decke des alpinen Flyschtroges im Raum Allgäu/Vorarlberg untersucht. Die Gesteinsserien sind stark tektonisiert, primäre lithostratigraphische Übergänge sind nur selten erhalten. An Hand exemplarischer Aufschlüsse wurde speziell für die basalen Serien dieser Decke (Aptychen-Schichten, Unt. Junghansen-Serie, Feuerstätter Sandstein) versucht, auf bio- bzw. lithostratigraphischem Wege Übergänge, die bisher erkannt bzw. vermutet worden sind, zu bestätigen oder neu zu erfassen. Für die Aptychen-Schichten wurden die Aufschlüsse im unteren Ränker-Tobel und an der Böigen Ach (Ob. Balder­ schwanger Tal) untersucht, da hier Übergänge zur Unt. Junghansen-Serie vorliegen sollen.
    Description: Strata of the Feuerstätt nappe (northern Penninicum) of the Alpine flysch trough in the Allgäu-/Vorarlberg area were studied. The series of this nappe are highly tectonized and primary 1ithostratigraphic transitions are rarely preserved. Previously recognized or assumed transitions in the basal series of this nappe (Aptychen-series, Lower Junghansen-series, Feuerstätt sandstone) were confirmed or reclassified in exemplary outcrops, using bio- and 1ithostratigraphical methods. All sediments were studied petrographically to determine sedimentological criteria. These studies prove that the sedimentological character of the Aptychen-series differs greatly from the Lower Junghansen-series and the Feuerstätter sandstone. The Aptychen-series contain sediments belonging to a pelagic carbonate facies. They are similar to the "Upper Austroalpine" Aptychen limestone. The Lower Junghansen-series, the Feuerstätt sandstone, and the Bolgen-conglomerat (Upper Junghansen-series) mainly represent a proximal flysch-facies. Since the Aptychen-series are of Upper Jurassic age, the contacts between these sediments and the enveloping flysch-series (Hauterivian/Barremian-Paleocene) must be of tectonic character. The results of the sedimentary petrographic studies suggest a common sedimentation trough for the Lower Cre­taceous series of the Faiknis-Tasna-nappe, the "Hauptflysch” nappe and the Feuerstätt nappe. Convergence between the Prätigau-flysch and the Feuerstätt nappe exists only in the Upper Cretaceous and the Lower Tertiary peroids.

    Description: The paleo-oceanography of the southeastern North Atlantic Ocean during the last 150,000 yr has been studied using biogenous and terrigenous components of hemipelagic sediments sampled close to the northwest African continental margin. Variations of oxygen isotope ratios in shells of benthic calcareous foraminifers in two cores allow the assignment of absolute ages to these cores (in the best case at 1000 yr increments). The uncorrected bulk sedimentation rates of the longest core range from 3.4 to 7.6 cm/ 1000 yr during Interglacial conditions, and from 6.5 to 9.9 cm/1000 yr during Glacial conditions; all other cores have given results of the same order of magnitude, but with generally increasing values towards the continental edge. The distribution of sediment components allow us to make inferences about paleo-oceanographic changes in this region. Frequencies of biogenic components from benthic organisms, oxygen isotope ratios measured in benthic calcareous foraminiferal shells, the total carbonate contents of the sediment and distributions of biogenic components from planktonic organisms often fluctuate in concert. However, all fluctuations which can be attributed to changes of the bottom water masses (North Atlantic Deep Water) seem to precede by several thousand years those which can be linked to changes of the surface water mass distributions or to changes of the climate over the neighboring land masses. Late Quaternary planktonic foraminiferal assemblages in the cores from the northwest African continental margin can be defined satisfactorily in the way that distributions of assemblages found in sediment surface samples from the northeast Atlantic Ocean have been explained. The distributions of assemblages in the northwest African cores can also be used to estimate past sea surface temperatures and salinities. The downcore record of these estimates reveals two warm periods during the last 150,000 yr, the lower one corresponding to the oxygen isotope stage 5 e (equivalent to the Eemian proper in Europe), the upper one to the younger half of the Holocene. Winter surface water temperatures during oxygen isotope stages 6, 4, 3, and 2 are remarkably constant in most cores, while summer sea surface temperatures during stage 3 reach values comparable to those of the warm periods during the Late Holocene and Eemian. Estimated winter sea surface temperatures range from 〉 16 °C to 〈 11°C, the summer sea surface temperatures from 〉 22 °C to 〈 15 °C during the last 150,000 yr. Estimates of the winter sea surface salinities fluctuate between 36.6‰ and 35.5‰, the higher values being restricted to the warm periods since the penultimate Glacial. Estimates for sea surface temperatures and salinities for two cores from the center of today's coastal upwelling region show less pronounced fluctuations than the record of the open ocean cores in the case of the station 12379 off Cape Barbas, more pronounced in the case of station 12328 off Cape Blanc. Seasonal differences between winter and summer sea surface temperatures derived from the estimated temperatures are today more pronounced in the boundary region of the ocean to the continent than further away from the continent. The differences are generally higher during warm climatic periods of the last 150,000 yr than during cooler ones. The abundance of terrigenous grains in the coarse fractions generally decreases with increasing distance from the continental edge, and also from south to north. The dominant portion of the terrigenous detritus is carried out into the ocean during the relatively cool climatic periods (stage 6, 4, later part of stage 3, stage 2 and oldest part of stage 1). The enhanced precision of dating combined with the stratigraphic resolution of these high deposition rate cores make it clear that the peaks of the terrigenous input off this part of the northwest African continental margin occur simultaneously with times of rapid sea level fluctuations resulting from large volume changes of the large Glacial ice sheets.

    Description: During the "Meteor“-Expedition to the Persian Gulf in March-May 1965, approximately 300 samples were collected. Most of them have been already studied by various authors in sedimentological as well as micropaleontological respects. 49 samples were selected for ostracode studies. These samples are arranged to form a long-axis section ("Laengsprofil“), and 4 shorter cross-profiles, perpendicular to the long-axis profile in the Persian Gulf and Gulf of Oman. 52 species of ostracodes in this area were specifically determined; 39 of them are described under open nomenclature. 13 species are already known from surrounding sea areas: 2 species from the Red Sea; 2 species from the east coast of Africa; 1 species from the Mediterranean Sea; and others from the Indian and Pacific Oceans. 12 species show close relationships to species from the Indopacific Ocean. The ostracode species found in the area can be grouped after the method of BRAUN-BLANQUT into 2 bioassociations. Association 1 with the following 4 characteristic species : Cytherella cf. pulchra, Loxoconcha sp. A, Neomonoceratina sp. A, Alocopocythere reticulata. Association 2 with 1 characteristic species: Ruggieria (Ruggieria) sp. B. The association 1 is widespread in the entire studied area of the Persian Gulf, where it is considered to characterize the shallow water region down to 200 m. The association 2 is restricted to the deeper water below 200 m of the inner part of the Oman Gulf. Only a few species known from the shallow water association of the Persian Gulf are present. Within the two ostracode associations mentioned above 4 zones from the total studied area could be related to the water depth. The zones A-D are characterized more or less readily by the relative abundance of certain species: Zone A : 7-30 m depth, on substrates of poorly coarse-grained clayey marl; Zone B: 30-94 m depth, on substrates of richly coarse-grained calcareous marl; Zone C: 94-1961208 m depth, on substrates of richly coarse-grained calcareous marl; Zone D: 196/208-500 m depth, on substrates of calcareous clay, poor in benthos. The regional and bathymetric distribution of the ostracode fauna in the area studied was compared in relation to 10 environmental factors: water depth, temperature, salinity, water density, O2-concentration, phosphate-silica contents, pH-values, stratification of the water body, water currents and type of sediments. The major environmental factors which appear to control the ostracode distribution are water depth (as a complex factor), O2-concentration and the type of sediment. At 3 stations (GIK01058, GIK01074 and GIK01204) species of the shallow water association were found together with a few bathyal species. These stations are situated at the outer Biaban shelf, in an area where the bottom water of the Persian Gulf flows down the slope towards the Oman Gulf. Several samples of the Zone B in the major part of the Persian Gulf show also a high species diversity containing a high percentage of subfossil ostracode carapaces. It is probable that the recent biocoenosis has been mixed with a late quarternary thanatocoenosis.

Meteor Forschungsergebnisse, Deutsche Forschungsgemeinschaft, Reihe C Geologie und Geophysik, Gebrüder Bornträger, Berlin, Stuttgart, C31, 21-48
    Publication Date: 2024-02-03
    Description: Surface sediments from 5 profiles between 30 and 3000 m water depth off W Africa (12-19° N) have been studied for their sand fraction composition and their total calcium carbonate and organic matter contents to evaluate the effect of climatic and hydrographic factors on actual sedimentation. On the shelf and upper slope (〈 500 m), currents prevent the deposition of significant amounts of fine-grained material. The sediments forming here are characterized by high sand contents (〉 60 %; in most samples 〉 89 %), low organic carbon contents (in most samples 〈 0.8 %), high median diameters of the sand fraction (120-500 µm), and by a predominance of quartz and biogenic relict shells (most abundant: molluscs and bryozoans) in the sand fraction. Median diameters of total sand fraction and of major biogenic sand fraction components (biogenic relict material, benthonic molluscs, benthonic and planktonic foraminifers) co-vary to some extent and show maximum values in 100-300 m water depth, reflectingthe sorting effect of currents (perhaps the northward flowing undercurrent). In this water depth, biogenic relict material is considerably enriched relative to wuartz, the second dominating sand fraction component on the shelf and upper slope, resulting in distinct calcium carbonate maxima of the bulk sediments. The influence of the undercurrent is also reflected in a northward transport of fine grained river load and perhaps in the distribution of the red stained, coarse silt and sand-size clay aggregates, which show maxima in 300-500 m water depth. They probably originate from tropical soils. Abundant coarse red-stained quartz on the shelf off Cape Roxo (12-130° N) suggests a southward extension of last glacial dune fields to this latitude. Below about 500 m water depth, current influence becomes negligible – as indicated by a strong decrease in sand content, a concomitant increase in sedimentary organic carbon contents (up to 2.5-3.5 %), and the occurence of high mica/quartz ratios in the sand fraction. Downslope transport, presumably due to the bioturbation mechanism, is indicated by the presence of coarse shelf-borne particles (glauconite, relict shells) down to about 1000 m water depth. The fine/coarse ratio (clay + silt/sand) of the sediments from water deoth 〉 500 m never exceed a value of 11 in northern latitudes (19° - 26° N), but shows distinct maxima, ranging from 50 to 120, at latitudes 18°, 17° 15°30', and 14° N in about 2000 m water depth. This distribution is attributed to the deposition of fine-grained river load at the continental slope between 18° and 14° N, brought into the sea by the Senegal and souther rivers and transported northward ny the undercurrent. Strong calcium carbonate dissolution is indicated by the complete disappearance of pteropodes (aragonite) and high fragmentation of the planktoic foraminifers (calcite) in sediments from water depth 〉 300-600 m. Fragmentation ratios of planktonic foraminifers were found to depend on the organic carbon/carbonate ratios of the sediment suggesting that calcite dissolution at the sea bottom may also be significant in shelf and continental slope water depths if the organic matter/carbonate ratio of the surface sediment is high and the test remain long enough within the oxidizing layer on the top of the sulfate reduction zone. The fact that in the region under study intensity and anual duration of upwelling decrease from north to south is neither reflected in the composition on the sand fraction (i.e. radiolarian and fish debris contents, radiolarian/planktonic foraminiferal ratios, benthos/plankton ratios of foraminifers), nor in the sedimentary organic carbon distribution. On the contrary, these parameters even show in comparable water depths a tendency for highest values in the south, partly because primary production rates remain high in the whole region, particularly on the shelf, due to the nutrient input by rivers in the south. In addition, several hydrographic, sedimentological and climatic factors severely affect their distribution – for example currents, dissolution, grain size composition, deposition of river load, and bulk sedimentation rats.

    Description: The nervous system in the tentacles of the sea anemones Tealia felina, Anemonia sulcata, Metridium senile and Cerianthus membranaceus was studied using light microscopic and electron microscopic techniques. \nBecause of the small dimensions of the nerve cells (6\xe2\x80\x947 \xc2\xb5m) and of the neurites (diameter 〈 1 \xc2\xb5m) satisfactory information could not be obtained using conventional histological techniques. \nElectron microscopic investigation showed that the nervous system can be divided into three parts: the plexus round the mesogloea, a nervous system between the muscles (obviously connected with the plexus) and sensory cells in the outer layer of the tentacle connected to the plexus by nerve fibres. The latter nerve cells with their fibres are arranged radially in the tentacle ectodermis. These are the only sensory cells discovered in the tentacles of the sea anemones. \nIn these radial neurites and in a number of neurites in the plexus, dense core granules are found. In the nervous system between the muscles and in a number of neurites in the plexus, opaque granules are found. Neurites containing dense core as well as opaque granules were never observed. Only in the radial neurites and in the plexus a yellow F(ormol) I(nduced) F(luorescence) was observed. Analysis of the emission spectrum showed that the F.I.F. had developed from a catecholamine (most probably noradrenalin). Therefore the dense core granules contain a catecholamine. \nOn the basis of morphological similarity, the neurites containing opaque granules may be identified as purinergic as proposed by Burnstock (1972), since the innervation of the muscles in the sea anemones very much resembles the innervation of smooth muscles in vertebrates. \nSynapses as described by a.o. Westfall (1973a) could not be demonstrated. However, desmosome-like structures were found between the epithelial cells and between the muscles, so that a non-neural conduction (c.q. myoepithelial conduction) is probable. This myoepithelial conduction may explain the presence of a \xe2\x80\x9csecond nervous system\xe2\x80\x9d postulated by Bullock & Horridge (1965) which is supposed to be a slowconductive system. A morphological indication for a \xe2\x80\x9csecond nervous system\xe2\x80\x9d has never been found. \nThe two transmitter substances mentioned (no indication was found for the presence of GABA and acetylcholine), i.e. a catecholamine, most probably noradrenalin, and a purine derivate, both have an excitatory function. The possible role of glutamate as an inhibitor has been discussed. Glutamate acts as a possible inhibitor, since it is released from contracting muscles and inhibits the contraction via an unknown mechanism. \nHydra was investigated and the findings were discussed in relation to the existing literature. Only the existence of synapses was discrepant, since these structures could not be demonstrated. \nRegarding the possible transmitters a catecholamine could be demonstrated with the F.I.F. method. A purinergic muscle innervation is possible in view of our experience with sea anemones.

    Description: The study of some newly collected material from the West Indies may justify a fourth paper on Caribbean Tenebrionidae in these \xe2\x80\x9cStudies\xe2\x80\x9d. Thanks to dr. P. WAGENAAR HUMMELINCK\xe2\x80\x99S collecting work, the Tenebrionid fauna of the Antilles and the adjacent South American mainland shores may be considered to be pretty well known \xe2\x80\x94 at least as far as the Melasomes are concerned. Thus zoogeographical conclusions \xe2\x80\x94 though not differing essentially from those published in 1962 \xe2\x80\x94 appear to have a rather solid basis. Unfortunately much less is known about planticolous Tenebrionids, which anyhow are relatively less interesting for zoogeographical purposes, than the geophilous ones.\nWe also had the privilege of consulting the collections of the I.N.R.A. at Guadeloupe (see MARCUZZI & D\xe2\x80\x99AGUILAR 1971) which considerably increased our knowledge of the Tenebrionid fauna of that and neighbouring islands. Several specimens on hand at the Institute of Marine Biology, Mayag\xc3\xbcez, proved extremely useful for obtaining a better knowledge of the Tenebrionid fauna of the old, sedimentary island of Puerto Rico. In a few single cases material from other sources (British Museum, Museum G. Frey and the private collection of the author) has been used.

    Description: Cercariae have been collected and studied from two sampling areas, situated at a distance of about 5 km of one another, South-East of Amsterdam.\nThirteen species are mentioned in this paper, seven of which are reported from the Netherlands for the first time. Two species are described in detail: an echinostome cercaria tentatively identified as Cercaria deficipinnata Khan, 1960, and a new xiphidiocercaria belonging to the group \xe2\x80\x9carmatae\xe2\x80\x9d, named Cercaria otiosa n. sp.\nThe cercarial fauna in the two sampling areas is compared, and possible causes of differences are briefly discussed.

    Description: The life cycle of the gorgonian Eunicella singularis has been studied with emphasis on larval behaviour, metamorphosis and annual growth. Planulae are found to have a mobile phase lasting from several hours to several days. Once settled, they metamorphose into a complete primary polyp in approximately four days. In the first year, budding will yield colonies of a height between 10 and 30 mm. Subsequently, average growth rates range from 14 to 33 mm year\xc2\xaf\xc2\xb9. Death may be due to several causes. Predators may partly denude the gorgonian branches, thus facilitating the settlement of epibionts, which in turn may invade the entire skeleton, slowly pushing back the living tissue of the gorgonian. Colonies may also be torn off their substratum by wave or current action, this process sometimes being speeded up when tall epibionts such as fast growing bryozoans enhance resistance to water movement. Once toppled, the gorgonians die by necrosis of their living tissues, or by being buried under sediment. Colonies of E. singularis are estimated to reach an age of approximately 25 to 30 years. Some data have been obtained on growth rates and life spans of two other Mediterranean gorgonians, Lophogorgia ceratophyta and Paramuricea clavata.

    Description: A primitive freshwater planarian, Eviella hynesae gen. et sp. nov. is described from Australia. It is characterized by its lack of eyes and pigment, possession of caudally branched oviducts, and fully fused testes. Although a primary bursa is absent, its function being taken over by the modified female genital canal, the female copulatory system is posterior to the male system. Despite this maricolan feature, and other similarities with primitive southern hemisphere freshwater planarians that have been classified in the Maricola, the present species is placed in the family Dugesiidae of the Paludicola. Evidence from its sensory organs suggests that it belongs on the main evolutionary line from which the majority of Australasian freshwater planarians have been derived.

    Description: This study deals with 272 Megachiroptera from the People\xe2\x80\x99s Republic of Congo, belonging to 13 taxa: Eidolon helvum helvum (Kerr), Rousettus aegyptiacus unicolor (Gray), Lissonycteris angolensis angolensis (Bocage), Myonycteris torquata (Dobson), Hypsignathus monstrosus Allen, Epomops franqueti franqueti (Tomes), Epomophorus cf. labiatus (Temminck), Epomophorus wahlbergi haldemani (Halowell), Micropteropus grandis Sanborn, Micropteropus pusillus (Peters), Scotonycteris zenkeri zenkeri Matschie, Scotonycteris ophiodon Pohle, and Megaloglossus woermanni Pagenstecher.\nOf these, Epomophorus cf. labiatus and Micropteropus grandis are recorded from this country for the first time. The known ranges of Epomophorus cf. labiatus and Micropteropus grandis are greatly extended towards the west. In morphology and zoogeography ten species correspond with populations to the north and, with the possible exception of both Scotonycteris species, to the south; towards the east the distribution of Rousettus aegyptiacus and both Scotonycteris species is possibly discontinuous. The two Epomophorus species and Micropteropus grandis are linked with populations towards the south and east only.\nSeasonal biannual reproduction is assumed for Epomophorus wahlbergi Epomops franqueti, and Micropteropus pusillus. Data on reproduction in other species are scarce or lacking.

    Description: Every new mammal or bird in the Amsterdam zoo, without exception, is kept in quarantaine for some weeks and until necessary standard checks are done. The number of mammals in the collection during the period 1967-1973 varied between 729 and 858 belonging to 172 to 208 species. In birds these figures were 1571 and 1803 specimens of 391 to 520 species (table I). The average percentage of deaths in mammals was 12.4% (table II) and in birds 13% (table III).\nThe causes of death (tables IV and V) are arranged under 15 headings for mammals and under 18 for birds; both numbers and percentages are given. During 1967, 1968, and 1969 there were many cases of Yersinia pseudotuberculosis in the nocturnal house. The troubles only stopped after vaccination of all animals already present in the house and of the new ones before housing them. Cases of non-identified infections in psittacine birds (53 victims) and penguins (19 victims) are provided. The same holds true for a skin disease in apes and diabetes in ruminants. A rather detailed report is given on cowpox in indian elephants in 1973. The three females of different age were affected; the male stayed free. All animals recovered after periods ranging from 17 to 57 days. One elephant had serious foot troubles in the same period, the most serious at the left forefoot. It took about 6 weeks before all animals recovered completely.\nThe survival rate of newborn mammals fluctuated between 59% and 66%, at a number of births fluctuating from 164 to 249 a year (table VI). The low rate of 56% for wild ruminants could be raised to 67% by feeding extra minerals to pregnant and nursing females. In birds hatched (table VII) the survival rates varied between 49% and 75%. The low figure is caused by the very bad results with ducks (in 1969 only 25% survival). By changing the accomodation we brought the figure for ducks up to 83% at the end of the period reported upon.

    Description: In the Colorado Beetle, the terminal filament cells resemble the epidermal cells which connect muscle cells with the cuticle, the so-called tendon cells. They contain many microtubules which have projections interconnecting them. The microtubules are also connected by these projections to desmosomes.\nThe tunica propria is a basement membrane-like layer of low elasticity. It separates the terminal filament from the germarium. The outer ovariole sheath is a muscle sheath which is continuous with the muscle sheath around the oviducts. The whole muscle sheath consists of a monolayer network. Sarcolemmal invaginations at the I band and at the Z line probably form part of one T system. The cuticle of the common oviduct has scales with long caudally directed spines.\nThe rostral attachment of the muscle sheath corresponds to the existing descriptions of tendon cells. The attachment of the muscle sheath to the cuticle of the common oviduct is different.

    Description: The sedentary ciliate fauna living on the body surface of Gammarus tigrinus and G. pulex from Dutch freshwater habitats has been investigated. Fourty-seven ciliate species are found, of which 43 belong to the order Peritrichida, suborder Sessilina, 3 belong to the order Suctorida and 1 belongs to the order Chonotrichida. Two new species in the genera Intranstylum and Pseudocarchesium are described.\nIt appears that there is a seasonal variation in the number of epizoic ciliates as well as in species composition. In general, the species with a contractile stalk are found on external, often fast-moving, body parts. Species with a noncontractile stalk seem to prefer more quiet and sheltered positions. After ecdysis there is a succession of the genera Epistylis and Zoothamnium, the latter becoming dominant on older exoskeletons.

    Description: Prof. Dr. Gerard Barendrecht was born on the 9th of October 1906 in Hilversum. After his final examinations in Kampen in 1923 there came a year of private studies of Greek and Latin. These formative years resulted in a continuing interest in the classical writers which he still reads as a relaxation from more strenuous tasks. On the other hand, the polders in the neighbourhood of Kampen gave the inspiration to the writing of the \xe2\x80\x9cGlorie van ons polderland\xe2\x80\x9d (\xe2\x80\x9cGlory of our polderland\xe2\x80\x9d).\nIn 1924 he entered the University of Amsterdam as a student in biology where he took his \xe2\x80\x9cdoctoraal examen\xe2\x80\x9d (master\xe2\x80\x99s degree) in 1929. His doctor\xe2\x80\x99s degree dates from the 20th of January 1932. His thesis \xe2\x80\x9cDie Corpora pedunculata bei den Gattungen Bombus und Psithyrus\xe2\x80\x9d is an elegant synthesis of his former work in the Dutch Central Institute of Brain Research as an adjunct-assistent to Prof. Dr. C. U. Ari\xc3\xabns Kappers and his work with his promotor, the entomologist Prof. Dr. J. C. H. de Meijere.

    Description: Arubolana imula, a new stygobiont isopod genus and species of the family Cirolanidae is described from Aruba (Netherlands Antilles). The new taxon has been discovered in an artificial tunnel, used for the production of industrial water, cut into calcareous rocks from marine origin which were rather recently uplifted above sea level (90,000-500,000 years B.P.). This is the first hypogean cirolanid that becomes known from the Lesser Antilles.\nThe quite characteristic and simplified morphology of the posterior maxillae and maxillipeds, the subterminal position of the appendix masculina, and the prehensile nature of the first and second pereiopods, distinguish the new genus very clearly from all other hypogean genera in the family Cirolanidae. The feeble development of the retinacula on the endite of the maxilliped indicates a certain affinity to the epigean genus Eurydice.

    Description: Regenerative capability of Plexaura flexuosa is investigated in experiments which simulate the injuries caused by predation of the ovulid snail Cyphoma gibbosum: partial or total removal of the coenenchyme from the axial skeleton.\nRegenerative growth of the coenenchyme is primarily induced by the possibility of linear extension of the axial epithelium; settlement of fleshy algae or e.g. Millepora (firecoral) on the axial skeleton inhibits the recovery of the coenenchyme. Coenenchyme growth is accompanied by evagination of the polyp cavity wall and by increased mesoglea production. The cellular basis for regeneration lies in the migration capability and morphogenetic plasticity of at least two cell types of the coenenchyme epidermis: interstitial cells and \xe2\x80\x9ctransitional\xe2\x80\x9d cells.\nRepeated removal of re-grown coenenchyme causes a decrease of the polyp density followed by the formation of new polyps. These are formed by an extra-tentacular budding mechanism which has its primordia in the epidermis of the coenenchyme.

    Description: The distribution of the larvae of Eylais discreta on the abdominal tergites of the host species Sigara striata, S. falleni and Cymatia coleoptrata is examined.\nOn S. striata and S. falleni the segments 3 and 4, on C. coleoptrata the segments 2 and 3 are successively preferred. There is but little influence of multiple infestations on this distribution.\nThe growth rate on the various tergites of S. striata is similar, while on C. coleoptrata a possible difference could not be proved statistically. The larvae of E. discreta generally hibernate on the host; during this phase there is little growth; not until March-April they start growing faster. The larvae on C. coleoptrata are retarded in growth compared to those on S. striata.\nThe larvae on S. falleni do not show any increase in size; this water bug species is immune to infestation by various Hydrachnellae.

    Description: Monthly samples of Gammarus fossarum have been taken in the Rh\xc3\xb4ne river system near Lyon, to determine the size composition and reproductive activity throughout the year. The acanthocephalan parasites of this gammarid species were also regularly collected. Furthermore, the intestinal tracts of a number of fishes (amongst others Thymallus thymallus), feeding mainly on Gammaridae, have been investigated for the presence of helminth parasites.\nG. fossarum reproduces throughout the year in the area near Lyon, but fluctuations in the rate of ovigerous females appear. A peak in the infestation of the gammarids by larvae of Pomphorhynchus laevis (Acanthocephala) occurred in autumn and a second peak, but a lower one, during spring. The fish hosts showed maximal infestations during the same periods, while during summer the incidence of Pom. laevis was low, both in the intermediate and in the final host.\nFrom the stomach contents of the fishes it seems that gammarids harbouring the invasive acanthocephalan larva (cystacanth) are selectively ingested.\nReproduction of G. fossarum seems not always to be inhibited at the presence of acanthocephalan larvae, since several infested female gammarids were found carrying eggs or juveniles in their brood pouch.\nThe occurrence of some other helminth parasites is recorded for the region near Lyon.

    Description: A study, by immunoelectrophoresis and immunodiffusion of the shared antigens in venom from 21 species of Viperinae and Crotalinae, representing 10 different genera, has produced a number of results of taxonomie significance which are summarized schematically in the dendrogram shown in fig. 1. For the most part these immunological data confirm the accepted classification of the Viperidae which is based on comparative morphology and biogeography. Some results, on the other hand, such as the isolated position of Atheris, need confirmation with more material. Some of the conclusions reached in this study, however, appear to be of significance for an understanding of the phylogeny of the group. Amongst the Viperinae, the genera Echis and Cerastes are apparently closely related to one another and more similar to the genus Bitis than to the genus Vipera. This latter genus is clearly composed of three groups of species with V. russelli occupying an isolated position. Amongst the Crotalinae, the genus Agkistrodon is quite distinct but Trimeresurus flavoviridis did not differ immunologically from the three species of Bothrops studied.\nIt would appear that the study of the shared antigens in snake venom is of taxonomie value both at the species group and the family levels. Occasionally, however, antigenic proteins in snakes venom are known to evolve rapidly, especially in isolated populations, and consequently the presence of a relatively small proportion of shared antigens should not necessarily be taken as evidence of a lack of affinity between two taxa.

    Description: It has been generally assumed that the influence of Charles Darwin\'s theory of evolution on Friedrich Nietzsche (1844- 1900) is to be understood in terms of Nietzsche\'s concept """"Obermensch"""" (overman). Hardly any attention has been paid to the question of the status of Darwin\'s theory in Nietzsche\'s philosophy. It is the purpose of this essay to answer that question.\nNietzsche\'s initial approval, and later criticism, of Darwinism is not limited to a specific theme of his philosophy, but is a part of his central philosophical concern, viz. the relation between nature and culture. Nietzsche approved of Darwin\'s theory as a natural basis for the explanation of human values. Later he is concerned about the basis of Darwin\'s theory and criticizes it because of its anthropomorphic presuppositions. This criticism is relevant to the present debate on the status of Darwin\'s theory of evolution and that of Nietzsche\'s theory of """"will to power"""".

    Description: Unter Anemonenfischen verstehen wir haupts\xc3\xa4chlich Arten der indopazifischen Gattung Amphiprion (Riffbarsche, Pomacentridae), die in Seeanemonen leben. Mariscal (1966) und neuerdings Allen (1975) haben die vielen Untersuchungen dieser Beziehung zusammengefasst. Aus der Literatur sind andere Anemonenfische kaum bekanntes handelt sich um einen Gobiiden aus dem Mittelmeer (Abel, I960) und ungef\xc3\xa4hr 14 Arten aus dem gleichen Lebensraum wie Amphiprion, darunter Pomacentriden (Stevenson, 1963), Cirrhitiden (Eibl-Eibesfeldt, 1964), Labriden, Blenniiden, Apogoniden, Anthiiden (Graefe, 1964). Bei all diesen Arten ist der Kontakt der Fische mit den Tentakeln der Anemone bei weitem nicht so deutlich ausgepr\xc3\xa4gt wie bei Amphiprion. Es scheint, dass die sch\xc3\xbctzende N\xc3\xa4he der Tentakeln zwar aufgesucht, direkter Kontakt aber meistens gemieden wird.\nNeuerdings werden Anemonenfische auch in der Karibischen See gefunden (siehe Karte). Smith (1973) beschreibt einen Cliniden von Panama. Hannau & Mock (1974) illustrieren eine zweite Clinidenart von den Bahamas. Colin & Heiser (1973) beschreiben zwei Apogoniden von Jamaica und Cura\xc3\xa7ao. Hanion & Kaufman (1976) f\xc3\xbcgen aus den Bahamas, von Jamaica und Honduras sechs weitere Arten hinzu: drei Cliniden, einen Gobiiden, einen Labriden und einen Pomadasyiden. Der vorliegende Bericht beschreibt 31 Anemonenfischarten aus 12 Familien von Cura\xc3\xa7ao, drei Viertel davon neu in dieser Hinsicht. Der Kontakt mit Anemonententakeln st\xc3\xb6rt all diese Fische nicht. Sie scheinen den Kontakt z.T. aufzusuchen. Ob die Vergesellschaftung eine Symbiose ist, ist noch nicht deutlich; sicher ist die Vergesellschaftung nicht so auff\xc3\xa4llig wie bei Amphiprion.

    Description: Groundwaters (in wells, springs, caves, macroporous interstitia...) of 29 Caribbean islands have been investigated. Only on the four islands off the coast of Venezuela (viz., Aruba, Cura\xc3\xa7ao, Bonaire, and Margarita) members of the suborder Ingolfiellidea (Crustacea, Amphipoda) have been encountered, altogether six species, of which three are described here for the first time. The zoogeographical implications of this limited range in the West Indies is discussed.

    Description: Branches of gorgonians belonging to four different Mediterranean species (Eunicella singularis (Esper), Paramuricea clavata (Risso), Corallium rubrum (Linnaeus) and Lophogorgia ceratophyta (Linnaeus)) were transplanted to different habitats by means of three different methods, and survival and growth rates were observed over periods ranging from three months to over two years. It was concluded that transplantation of animals still fixed on their natural substratum is to be preferred over transplantations involving artificial devices. Transplanted adult branches of all four species tolerate conditions under which the species are not usually encountered. Tolerances or preferences of larval and juvenile phases must account for these discrepancies. Transplants never survived in shallow waters. Algal competition, abrasion and mechanical destruction due to turbulent water conditions, and in some cases high irradiance values are among the lethal factors. In deeper water, sedimentation is also fatal, although in nature some colonies survive under similar conditions.

    Description: As a working hypothesis it is supposed that in the teleost Brachydanio rerio, the muscle contractions, the growth, and probably some other factors, cause the first changes in the shape of the somites. Furthermore, the movements of the embryo could yield the forces by which the somites are brought to their theoretically optimal shape.\nIn order to test this hypothesis, we investigated the somite shape and structure of spontaneously immobile embryos. Although the results are difficult to interpret, they certainly do not contradict the hypothesis.\nFor further analysis we applied two kinds of lesions in order to immobilize early embryos: removal of the brain, and damage to the midbody somites. The results of these experiments indicate that both the development of the shape of the somite and the arrangement of the muscle fibres are dependent on movements of the embryo.

    Description: Dugesia gonocephala (Dug\xc3\xa8s, 1830) and D. polychroa (Schmidt, 1861), collected from the Greek island of Corfu, have been investigated karyologically. The former is a sexual diploid (2n = 16) in which all the chromosomes are metacentric. The latter is a sexual diploid (2n = 8) with one submetacentric and three metacentric chromosome pairs.\nWithin the Dugesia lugubris-polychroa complex seven biotypes are known. The karyotype of D. polychroa from Corfu is most similar to biotype G from the western Mediterranean. However, there are subtle karyological and morphological differences between the two forms and thus the Corfu population is not assigned to biotype G but is considered to have been derived independently from the basic biotype A. Thus it represents an eighth biotype within the species group.
